Mr Sinister: He has no remorse for bringing pain onto others, no respect for the dead just rob graves for the name of what he believes, made the morlocks and then kills them! Right after they made a civilization in the sewers and then just ends their lives as quick as he gave them life. Cloning Jean and having the clone go for Havoc just messing up Scott to a major level. Started Inferno both scientifically and supernaturally. He is the mad scientist that is brought to the next level.

They way things get changed, retconned, and rewritten in Marvel, it's as if no one in that universe is truly evil...

- Dr. Doom was perceived by 'the panther god' as being an honorable man

- The New Mutants recently tried to portray Mephisto (pretty much the embodiment of evil) as a good guy who is just misunderstood.

- Sabertooth swings back and forth between evil murdering bastard and good guy who is simply not understood.

As for me, I currently see Tony Stark as the most evil bastard on the planet... and yes, it goes back to Marvel Civil War and hew as written to be the bad guy... He intentionally arrested people whom the law had no sway over, and put them in the negative zone so that they would have no civil rights and he could do whatever he wanted to them. he said this to Peter Parker.... To pretend to be good, when actually doing evil.. THIS is truly evil...

Carnage, he's not the most powerful or anything. But he's one of the few characters that have no good in them at all. Most villains have reasons behind their actions whether it be personal gain or vengeance or something else they all have a motive, I'm not justifying their actions but they have motives behind them. Carnage doesn't he's just bad for the sake of being bad, he's just evil because he likes and it brings him pleasure to do evil. Others like Doom, Thanos, Green Goblin, etc. they're all evil no doubt but they have motives bgibd their evil actions, Carnage is just bad for the sake of being bad and he likes it that way. That makes him the most evil...

@turoksonofstone: We know you hate Stan but seriously he didn't do anything worse than anyone in comics at the time was doing. Back then there wasn't room to share so people acted like assholes its a business get over it

bbbbbbbbbbThe obvious evil is not the most dangerous... It's the evil that disguises itself as good that causes the most harm... Some of you may have read that, "satan will appear as an angel of light..." He won't show up, looking like an ugly monster. He won't be on fire, wielding a pitchfork, shouting, "I'm evil and here to do you harm!" He will look like your best friend...a charity worker....a police officer... or Tony Stark....
